Question

What is the difference between a fissure of volcano and crater of a volcano?

Answer 1

Feature	Fissure of Volcano	Crater of Volcano
Definition	A fissure is a long, narrow crack or opening in the Earth’s crust through which magma, gases, and lava escape to the surface during an eruption.	A crater is the opening at the top of the volcanic vent or neck through which lava is ejected. It is typically a circular depression.
Location	Fissures occur as cracks on the sides or surface of the volcano or the Earth’s crust.	The crater is located at the summit or top of the volcano’s vent.
Shape	Fissures are elongated, linear openings.	Craters are usually circular or bowl-shaped depressions.
Function	Fissures allow magma and gases to escape through a crack, often causing lava to flow out over a wider area.	The crater serves as the main vent’s outlet, concentrating the eruption from the magma chamber in one place.
Formation	Formed due to the splitting or cracking of the Earth’s crust under pressure.	Formed by the explosive ejection of volcanic material and lava from the vent.
